REG EN ERATIVE GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 706,831, dated August12, 1902.

Application filed May 16,1902J'Seria11l0. 107,643. (No model.)

known as regenerative burners,in which the gas is highly heated, andconsists in certain improvements in construction which will be fullydisclosed in the following specificationand claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a side elevation, partly in section; Fig. 2, anenlarged detail of the'lower portion of the structure, showing the partsin perspective; Fig. 3, a top plan view of the upper end of thecombining-tube which constitutes the burner; Fig. 4, an enlargedsectional detail of the upper end of the mixing-chamber.

the numerals thereon, 1 indicates the head, adapted to be attached tothe usual gas-fitting, is provided with lateral branches 2 and 3, whichextend upward and connect with a regenerative chamber 4,'the branch 2serving to conduct gas to said chamber and the branch 3 serving toconduct heated gas from the chamber and deliver it to the verticalbranch 5, provided with a reducer 6 for limiting the discharge or flowof gas, perforations or slots 7 for admitting, atmospheric 'air tosupply the necessary oxygen to the gas to render it combustible, and ahood 8, conical,

in transverse section, to confine the air around the slots 7. The sizeor area of the openings 7 is made to supply the necessary quantity ofair to insure perfect combustion of the gas.

9 indicates a tapering gas and air mixing or combining chamber or tubesupported between the branches 2 and 3 andthe air and gas therein heatedby the hot gas flowing through the tube 3 on its way to the dischargebranch 5. The branches 2 and 3 embrace the tube 9 on opposite sides andsecure the tube in position over the hood 8, and the hot gasfand air insaid tube produce the initial heating of the gas flowing through branch2 -onits Way to the regenerator 4.

On the tube 9 is a collar 10, having lateralarms 11 to support a globe12, (shown in dotted lines,) and the conical upper end of said tube isslotted at 13 and provided with a nut 14 for regulating the discharge ofthe gas and air by adjusting said nut to contract the overlappingmembers 15 or to allow the same ;to expand.

The: branches 2 and 3 are bent outward at 1616 to afford space toreceivethe'mantle 17, which is suspended from the lower part of theregenerator 4 by a hook-18 or similar device engaging an eye 19 on theregenerator. I Byinclosing the upper ends of th'ebranches 2-and 35withinthe globe 12 and by placing the regenerator 4 directly above the mantle17 in direct line with the ascending heat from the burning gas the gasin the branches and in the regenerator becomes highly heated andrarefied and when commingled with the air,

which is also heated in the tube 9, burns with great intensity andrenders the mantle perfectly incandescent. Reference being bad to thedrawings and Having thus fully described my invention, what I claim isr 1. A regenerative gas-burner having ahead provided with gas-conductingbranches, a regenerator connected toand supported by said branches, agas-discharge branch provided with means for admitting air thereto, anda tapering gas and air mixing and heating chamber having a contractibleand expansible discharge end.

2. A regenerative gas burner having a head provided with gas-conductingbranches, a re generatorconnected to and supported by said branches, agas discharge branch provided with means for admitting air thereto and aconical hood surrounding the branch, and a tapering gas and air mixingand heating chamber engaged by the gas conducting branches and providedwith an adjustable discharge end.

3. A. regenerative gas-burner having a head provided withgas-conductingbranches, a regenerator connected to andsupportedl by said branches, agas-discharge branch provided with means for admitting air thereto, ataper= ing gas and air mixing and heating chamber supported by thegas-conducting branches, engaged by the gas-conducting branches, a meansfor controlling the discharge end of collar on said tube, a globesupported by said said mixing and heating chamber, and a collar, and amantle suspended from the re-/ mantle suspended from the regenerator.generator. I In testimony whereof I affix my signature :5

4. A regenerative gas-burner provided with in presence of two Witnesses.gas-conducting branches, a regenerator con- EUGENE H. KELLY. nected toand supported by said branches, a Witnesses: gas-discharge branch, atapering gas and air HERMAN KUBANET,
